Book a vet visit

This is not usually an emergency on its own – contact your vet if it lasts, gets worse or your dog seems unwell in any other way. Tear staining is brown, pink or red staining that runs from the corner of the eyes and is often harmless, although it could be caused by an eye problem.

  • Recently developed tear staining

  1. Contact your vet if it is new or concerning.
  2. Note when it started, how often it happens and what else you see.
